TAKE-UP MECHANISM FOR LOOMS.

Specification of Letters Patent.

Patented Nov. 26, 1907.

Application filed January l7,1906- Serial No. 296,467.

Up Mechanism for Looms, of which the following is a specification.

My invention relates to take-up mechanism for looms, and moreparticularly to a releasing mechanism for the winding-up roll, and to animprovement on the releasing mechanism for the winding-up roll, shownand described in U. S. Letters Patent, No. 646,614,in which thewinding-up roll for the woven fabric is supported in vertically movingsupports and is pressed upwardly, and yieldingly held against thetake-up roll by springs, and a foot treadle mechanism is employed forlowering the winding-up roll from engagement with the take-up roll, toremove said winding-up roll from the loom, or

to adjust the fabric on the winding-up roll. It has been found inpractice, that in the use of the releasing mechanism for the windinguproll, shown and described in said patent, when the operator replaces awinding-up roll in place of the winding-up roll removed, and operatesthe treadle mechanism to allow the new winding-up roll to be raised intoits normal position, in yielding engagement with the take-up roll, thereis a liability of the fingers of the operator being caught between thewinding-up roll and the take-up roll.

The object of my invention is to provide a supplemental mechanism,adapted to be combined with the releasing mechanism for the winding-uproll, shown and described in said patent, by means of which the fullwinding-up roll is held in its lowered osition, preparatory to beingremoved from t e loom, an the winding-up roll which replaces the fullwinding-up roll is also held in its lowered position, and is allowed tobe raised into its normal position, in yielding engagement with thetake-up roll, through manually operated means, without operating thefoot treadle mechanism as required in said patent; the manually operatedmeans controlling the upward movement of the windingup roll.

My invention consists in certain novel features of construction of myimprovements, as will be hereinafter fully described.

I have shown in the drawings a take-up mechanism for looms, and areleasing mechanism for the winding-up roll combined therewith, ofsubstantially the same construction and operation as shown in saidpatent, No. 646,614.

Referring to the drawings :Figure 1 is a front view of the take-upmechanism with my improvements combined therewith, looking in thedirection of arrow a, Fig. 2. Fig. 2 is a vertical section, on line 2,2, Fig. 1, looking in the direction of arrow 1), same figure. Fig. 3corresponds to Fig. 2, but shows the full winding-up roll in its loweredposition, and shows the releasing mechanism for the winding-up roll inthe opposite position from that shown in Fig. 2. *ig. 4 1s a sectionalplan View of the releasing mechanism, taken at a point indicated by line4, 4, Fig. 1, looking in the direction of arrow 0, same figure.

In the accompanying drawings, 1 are the loom sides or ends, 2 is thebreast beam, 3 a guide-roll, 4 the take-up roll, 5 a guide-roll, 6 thewinding-up roll, 7 vertically moving arms or supports, having recessedupper ends 7 to receive the journals 6 on the ends of the winding-uproll 6. The vertically moving arms or supports 7 for each end of thewinding-up roll 6, have in this instance a hooked projection 7 at theirupper end adapted to extend over the flanged edge 8 on the verticallyextending stands 8, see Fig. 4, which are secured at their upper end tothe breast beam 2, and at their lower end to the loom sides 1.

The vertically extending stands 8 act as guides for the upper ends ofthe vertically moving arms or supports 7 for the windingup roll 6. Thelower end of each vertically moving arm or support 7 is made forkedshape, and one of sald arms, the one shown at the left in Fig. 1, ispivotally attached, in this instance to a side projection 9 on a foottreadle 9, the hub 9 of which is loosely mounted on a shaft 10 whichextends transversely through the loom, and is loosely mounted at eachend in bearings 11 on brackets 11, secured to the cross girth 1 of theloom. The lower forked end of the other supporting arm 7 is in thisinstance pivotally attached to an arm 12, the hub 12 of which is securedon the rock shaft 10, by a set screw or bolt 13, see Fig. 1. A secondfoot treadle 14 extends along side of the foot treadle 9, and has aprojection 14 thereon, which extends under and is adapted to be engagedby the foot treadle 9.

The hub 14 of the foot treadle 14 is fast on the rock shaft 10, in thisinstance secured thereon by two set screws or bolts 15, see Fig. 2.

The windingup roll 6 is held in yielding engagement with the take-uproll 4, in this instance by two spirally coiled springs 16, at each endof the loom. One spring 16 is attached at its lower end, in thisinstance to the foot treadle 9, and at its upper end to a projection 8on the stand 8. The other spring 16 is attached at its lower end to thelever or arm 12, and at its upper end to a projection on the stand 8,see Fig. 1. The take-up roll 4, and the winding-up roll 6 are operatedby a system of gears, shown at the right in Fig. 1 in the ordinary andwell known way, and therefore the operation thereof does not need to bedescribed herein.

All of the above described parts are, and may be of substantially thesame construction and operation as similar parts shown and 7 described1n said patent, N 0. 646,614.

I will now describe my improvements, which, as above stated, are adaptedto be combined with the take-up mechanism, and the releasing mechanismfor the winding-up roll, shown and described in said patent, No.646,614, and are employed to lock and hold the full winding-up roll inits lowered position, preparatory to being removed from the loom, andalso to hold and lock the new winding-up roll in its lowered position,and allow of the same being raised into its normal position, in yieldingengagement with the take-up roll, by the manual operation of theoperator.

' At one end of the loom, in this instance the left hand end, in abearing 17 on the upright stand 8, is loosely mounted the horizontallyextending shaft 18, which extends in a direction at right angles to thewinding-up roll 6. On the outer end of the shaft 18 is in this instancefast the hub 19 of a handle 19. On the inner end of the shaft 18 is fasta worm 20, having worm teeth thereon of the desired shape. Extending upfrom the hub 9" of the foot treadle 9, is an arm 9, see Fig. 2. To theupper end of said arm 9 is pivotally attached I the forked end of atoothed latch 21, see Fig. 4. The toothed latch 2 1 has in this instancea side bend therein, as shown in Fig. 4, so that its free end willextend over and in alinement with the shaft 18, carrying the worm 20.The latch 21 has teeth 21 thereon, of a shape adapted to engage with theworm teeth on the worm 20. The toothed part of the latch 21 ispreferably held in engagement with the worm 20 by gravity, but a lightspring shown by broken lines, 22, in Fig. 2, may be employed, to hold inthe position shown in Fig. 2, With its' toothed end resting on the worm20. As the woven fabric 23 is wound on the windingup roll 6, thewinding-up roll is moved downwardly, the springs 16 allowing thedownward movement of the supporting arms 7. The downward movement of thesupporting arms 7, causes the downward movement of the treadle 9 and thearm 12, and the rocking of the shaft 10; and the downward movement ofthe treadle 9, through arm 9', causes the latch 21, at its toothed end,to be moved outwardly, or in the direction of the arrow Fig. 2, saidtoothed end passing freely over the teeth of the worm 20, which isstationary. When the windingvup roll 6 is filled and ready to be removedfrom the loom, the operator presses downwardly the foot treadle 9, andthrough the engagement of said treadle with the foot treadle 14 fast onthe shaft 10, theshaft 10 is rocked, and with it the arm 12, to movedown the supporting arms 7 of the windingup roll 6. The downwardmovement of the treadle 9, causes the movement of the arm 9", and theforward movement of the toothedlatch 21, to its extreme outer position,as shown in Fig. 3. The engagement of the toothed part 21 of the latch21 with the stationary worm 20, as shown in Fig. 3, holds the toothedlatch in position, and through arm 9 holds the treadle 9 in its loweredposition, and also the arm 12' at the op osite end of the loom, andconsequently ho ds the supporting arms 7 in their lowered position. Thefull winding-up roll 6, shown in Fig. 3, may now be removed and a newwinding-up roll substituted therefor. After the new winding-up roll issubstituted, the operator turns the handle 19 on the shaft 18 by hand,and rotates said shaft 18, and with it the worm 20; the rotation of theworm 20, in engagement with the toothed latch 21, allows said latch 21to be moved inwardly, and allows the springs 16 to act to raise thetreadle 9 and the arm 12, and with them the supporting arms 7 of thewinding-up roll 6, into their raised position, shown in Fig. 2. Theengagement of the toothed latch 21 with the worm 20 controls andregulates the action of the springs 16, and said springs cannot operateto raise the supporting arms 7 for the winding-up roll 6, exceptaccording to the movement of the toothed latch 21 by the revolution ofthe worm- 20, as will be well understood, unless said latch 21 israised, and released from engagement with the worm 20.

The advantages of my improvements will be readily appreciated by thoseskilled in the art they are of simple construction and operation, andare adapted to be applied to the take-up and releasing mechanism of thetype shown and desoribed in said patent, N 0. 646,614.

It will be understood that the details of construction of myimprovements may be varied if desired.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. In the take-up mechanism of a loom, thecombination with vertically extending guide-ways, and vertically movingsupports for the winding-up roll, and means for yieldingly holding saidsupports in their raised position, and means for lowering said supportsto lower the winding-up roll, said lowering means consisting of leversor arms connected with said supports and mounted on a rock shaft, andsaid rock shaft, and means for rocking the same, of means for holdingsaid vertically moving supports in their lowered position, and manuallyoperated means for controlling the upward movement of said supports tomove the windingup roll into its normal raised position.
